Dear Chopper: For to check everything you can do two things: first try your 7000 and invert the cable conection between the cartridge and tonearm ( left side in right side and right side in left side position ), if you have sound from that channel ( that in the normal wire position you have not ) then the problem is not the cartridge. Second, try the Clearaudio like a MC cartridge ( with very low volume position ): MC position switch or through the stepup transformer and " see " what happen.
Regards and enjoy the music.
